This is probably the closest that HeroForge has to making a "Feral" character. And it's surprisingly accurate for what I envisioned for a Prickle Hare Dragon. (at least when it's much older, but not quite at "Ancient" status.) Not sure about the coloring, but I just didn't want it to be mistaken for a Jolteon as they do possess similar traits with each other. The main difference between an older Hare Dragon and it's youngling counter parts is how similar they are to ordinary rabbits. As a Prickle Hair Dragon grows older, it's horns begin branching out much like deer antlers. Their quil like fur becomes significantly harder and form a natural armor. It doesn't quite lose it's magical quality of making creatures that are stabbed with it go into a beserk state. (The exact opposite of a Powdered Hare Dragon)

I can't tell you everything that makes a Prickle Hare Dragon different from it's cousins (The Powdered Hare Dragon and the Valley Hare Dragon). However, the most interesting factoid about this particularly aggressive cousin (aside from their natural paranoia) is their love of milk and milk byproducts. While Powered Hare Dragons like corn as their treasure, Prickle Hare Dragons would collect cheese. Fresh milk seems to be the only thing that truly calms a Prickle Hare Dragon down, so much so that it's practically hypnotic. They'd steal cows, if not for the fact that they have trouble working the utters... oh and their natural paranoia and distrust of any living creatures. I'm sure you can imagine that it's different case for when they're wormlings.
